CHARLES E. CHAVEZ AND FEDERICO GARCIA SANCHEZ, OF KEY WEST, FLORIDA.

BOAT-PROPELLER.

Specification of Letters Patent.

Patented N ov. 14, 1916.

Application led December 22, 1915. Serial No. 68,249.

To all cl2/0m t may concern:

Be it known that we, CHARLES E. CHAVEZ, a citizen of the United States, and a resident of Key lVest, county of Monroe, and State ofFlorida, and FEDERICO GARCIA SANCHEZ, a citizen of Cuba, and a resident of Key lVest, in the county of Monroe and State of Florida, have invented a new and Improved Boat-Propeller, of which the following'is a full, clear, and exact description.

Our invention has for its object to provide means for propelling a boat having a stern propeller shaft, and side propellers mounted on a transverse shaft, there being means for operating the two shafts from a transverse shaft having a crank at each end to which arms on the operating handle are articulated.

Additional objects of the invention Will appear in the following specification, in which the preferred form of our invention is described.

In the drawings similar reference characters denote similar parts in all the views, in which- Figure l is a side sectional fragmentary view showing a portion of a boat in which our propeller is mounted; Fig. 2 is a plan view showing our invention; and Fig. 3 is a sectional view on the line 3-3 of F 2.

By referring` to the drawings, it will be seen that a frame 5 is provided havingtransverse bearings 6 in which a transverse shaft 7 is journaled, this transverse shaft 7 have ing two cranks 8, one at each end, to which are articulated at 9 arms 10 on a yoke 11 having a handle 12 by whichthe yoke with its arms 10 may be operated to rotate the cranks, thereby rotating the shaft 7. To insure an even rotary movement of the shaft 7, we prefer to provide it with a fly-wheel 0 13. Extending from a side portion 5a of the frame 5 there is a'horizontal frame men ber 5b which has a vertical bearing -14 in which the top of a shaft 15 is journaled, the bottom of this shaft 15 being journaled in the bearing 16 in a transverse frame member 5. Secured to the shaft 15 there is a bevel gear wheel 17, with which meshes a gear 18 on the transverse shaft 7, there be- Copies of this patent may be obtained for ve cents each, by addressing,` the rotate the shaft 7 by ing also another gear 19 which is secured to thc shaftV l5, this gear 19 meshing with a gear 20 which is secured to a stern wheel propeller shaft 21 journaled in bearings 22, a propeller 23 being secured to the rear of this shaft 21, and the said shaft 21 being mounted at the stern 24 of a boat 25 in the customary manner.

Vhen operating the propeller, it is possible for the boatman to sit on a seat 26 and means of the handle 12 through the means which has been described, the shaft 7 rotating the propelling shaft 21 by the means set forth.

If the boatman desires to make use of a side propeller in addition to the stern propeller 23, this may be done by connecting a sprocket wheel 27 shaft 7 by a sprocket chain 32 with a sprocket wheel 28 secured to a shaft 29 journaled in bearings 30. This shaft 29 is disposed transversely and extends through the sides of the boat in a manner well understood, with propellers 31'mounted on the nds of the shaft 29 at the outer side of the oat.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:

In a boat propeller, a frame with transverse bearings, a transverse shaft journaled' in the bearings, a crank at each end of the shaft, an operating handle having two arms, one articulated to each crank, a vertical shaft journaled in bearings in theframe, gearing connecting the two shafts, a stern propeller shaft, gearing connecting the vertical shaft with the stern propeller shaft, a transverse propeller shaft for a side propeller, and means connecting the first transverse shaft with the last mentioned transverse shaft forV operating the latter.

which is secured to theY In testimony whereof we have signed our Y names to this specification in the presence of two` subscribing witnesses.
